Coordination procedures

Coordination is bilateral/multilateral process, aimed at interference-free operation of existing and planned systems of administrations. From a regulatory point of view there are two types of coordination between administrations: mandatory and voluntary. Mandatory coordination covers: (a) coordination of terrestrial services in the frequency bands shared with the space services above 100 MHz under provisions RR9.16, RR9.18 and RR9.19; (b) Obtaining agreement for terrestrial services in the bands which are indicated in the Article 5 footnotes making reference to provision RR9.21; (c) Coordination of stations of non-planned terrestrial services operating in the bands and geographical areas covered by different Regional Agreements (e.g. GE85-EMA) vis-à-vis planned services; and (d) coordination required by some WRC Resolutions (e.g. Resolution 612 (WRC-12)). Voluntary coordination: direct coordination between administrations concerned without involvement of the Radiocommunication Bureau, e.g. coordination of cellular networks in border areas

Coordination with space services under RR9.16, RR9.18 and RR9.19

Coordination of terrestrial stations vis-à-vis receiving earth stations in the bands above 100 MHz shared with equal rights between terrestrial and space service and allocated to space services in space to Earth direction of transmission if the terrestrial station is located in the coordination area of an earth station (RR9.16 or RR9.18)

Coordination of transmitting terrestrial station vis-à-vis typical earth station included in the service area of a space station in the broadcasting-satellite service in the bands shared with equal rights between terrestrial and broadcasting-satellite service (RR9.19).

Coordination under RR9.21

Obtaining agreement for a terrestrial station operating in the bands mentioned in a footnote to the Table of Frequency Allocations of RR Article 5, making reference to the provision of RR9.21.

Voluntary coordination

​Coordination between administrations concerned according to Article 6 of the Radio Regulations (without involvement of the Radiocommunication Bureau), e.g. coordination of cellular networks in border areas.
